NRS social grade

The NRS social grades are a system of demographic classification used in the United Kingdom. They were originally developed by the National Readership Survey to classify readers, but are now used by many other organisations for wider applications and have become a standard for market research.[1] They were developed over 50 years ago and achieved widespread usage in 20th century Britain. Their definition is now maintained by the Market Research Society.[2]

The distinguishing feature of social grade is that it is based on occupation.

Casual or lowest grade workers, pensioners, and others who depend on the welfare state for their income

8%

The grades are often grouped into ABC1 and C2DE; these are taken to equate to middle class and working class, respectively. Only around 2% of the UK population is identified as upper class,[4] and this group is not separated by the classification scheme.
